Josef Prusa born and raised in the Czech Republic was never satisfied with things as they are. Fascinated with the way things work, Josef would find better ways on how he could improve it. In several cases, totally change to a brand new use than what it was originally designed for. At the age of 18 he already published his own chapter in book by O'reilly called iPhone hacks. Since then he makes more and more uses for stuff. In 2010 his main focus of work has shifted to developing Open Source 3D printer project called RepRap (http://reprap.org) and Open Source Hardware generally.
